Gar, a half Terran, half Antal (a giant bipedal cat-like race) geneticist, is tasked with locating a genetic mutation bringing the Antal people to the brink of annihilation. But the mutation is only one piece of a grand puzzle-like conspiracy that could enslave an entire race and turn the majestic realm of Alvar into a swampy wasteland ruled by insectoid conquerors. Ideas explored include prejudice, acceptance and unity, but ultimately, the questions asked are deeply spiritual in nature.
